for 1k... you're either going to get wheels and suspension in the mid-low range or high quality one or the other. But the better the tire, the better performing... so that is really where you're going to have to pay/ pay attention.
You can go buddyclub p-1 (~$150 a wheel) = 600
Hankook v2 (~$63 per wheel) = 252
Suspension you can go FF type 1 - ~$550
So you're still over budget, but check the boxes.
But you'll have to worry about over/understeer conditions with the lower/ stiffer dampers and stickier/lighter wheel/tire.
I've had kongis that have bent under track conditions, so I tend to stay away from them now.
